in thread group based array sort

that's good and fine if the data came in the sorted tree order, which it doesn't in my situation. :-) think like pulling from a database, where the order is unknown and i'm not allowed to do ORDER BY in my sql.

    While I really think using Sort::Tree is probably the best option, here is a purely iterative solution. It has the following requirements:
  • IDs will always be numerical
  • Root level nodes will always have a parent of 0
  • Probably a few others Cheers - L~R
      thanks! I'll give them both a shot.
